Astudent runs 100 meters in 11 seconds. what is the speed of the student?

Before we get into solving this, let's break down how we solve for Speed.
Speed is solved by Distance divided by Time, or, S = D / T

Distance can be measured in:
Inches, centimeters, miles, kilometers, meters, feet, yards, etc.

Time can be measured in:
Seconds, milliseconds, minutes, hours, days, weeks, etc.

We have 100 meters, which is a measure of distance, defined in the examples provided above.

We have 11 seconds, which is a measure of time, defined in the examples provided above.

So, we have 100 for D, and 11 for T.

S = D / T

Let's plug our numbers in.

S = 100 / 11

Divide 100 by 11 to solve for the Speed.
100 / 11 = 9.09~ (terminating decimal).

Remember to use our measure of distance divided by our measure of time as our unit of measurement squared for the solution.

9.09 m/s^2 is your answer.

I hope this helps!
